Let's divide 539971 by 12
Our goal is to divide 539971 by 12.

On to step 1:
The number 12 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 12

Going ahead to step 2:
12 goes into 53 4 times with a remainder of 5.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 48 from 53 leaves us with 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 12

Moving on to step 3:
If we divide 59 by 12, we get 4 and a remainder of 11.
Put 4 as the next digit of the answer. 
Result so far: 44.0
The remainder is 11 after subtracting 48 from 59.
Append the next digit (9) from the dividend to 11 and continue with: 119 / 12

On to step 4:
12 goes into 119 9 times with a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 449.0
The remainder is 11 after subtracting 108 from 119.
Fetch the next digit (7) from the dividend, attach it to 11 and continue: 117 / 12

Step 5:
If we divide 117 by 12, we get 9 and a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 4499.0
Subtracting 108 from 117 leaves us with 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 12

On to step 6:
12 goes into 91 7 times with a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 44997.0
The remainder is 7 after subtracting 84 from 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
If we divide 70 by 12, we get 5 and a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 44997.5
Subtracting 60 from 70 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
The number 12 fits into 100 8 times, leaving a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 44997.58
If we take 96 away from 100, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 9:
40 divided by 12 is 3 with a remainder of 4.
The next digit of our result is 3. 
Result so far: 44997.583
If we subtract 36 from 40, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 10:
If we divide 40 by 12, we get 3 and a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 44997.5833
If we subtract 36 from 40, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

After the division, we end up with 44997.5833 and a remainder of 4e-05.
